Periodic Elements Material Object Decorative Acrylic Cube with Real Na/Mn/Bi Samples Gift for Collection 5cm New NO5146

Features:

1. HIGH QUALITY: Made of high quality acrylic, which is long-lasting and highly decorative with clear appearance.

2. BEST GIFT: A perfect gift for chemistry or science lovers everywhere! Great for display on desks, tables, or in the classroom.

3. Element 11: Sodium is a gleaming metal that looks identical to the backing of a mirror when not bound up chemically with dancing partner chlorine (or practically anything else). Safely suspended in the middle of this crystal clear block of acrylic. Barring some very determined effort it will stay probably remain complete until the day the sun swallows the earth!

4. Element 25: Manganese is a rather common metal it is actually only rarely available as a standalone metal at all; and then only typically as powder or unattractive electrolytic "chips" shiny on one side and the other mottled and oxidized. In an altogether different category we find lab created nodules made for studying naturally occurring alloys rich in manganese that are found on the ocean floor.

5. Element 83: Bismuth is a dense metal with about 86% the density of lead. The symbol for bismuth is Bi. It has an atomic weight of 208.9804 and its atomic number is 83. The iridescent colors seen on the surface of the crystals if formed during oxidation. The iridescence is due to very thin layers of oxidation and are allowed to occur for purely aesthetic reasons; a little thicker here, a little thinner there, in each case a different color is produced due to light refraction.

Notice:

Actual color may be slightly different from the image due to different monitor and light effect.

Please allow 1-3cm deviation due to manual measurement.
